The team has taken it easy on Salazar, who will turn 24 years old on Tuesday. He could start the season as the fifth starter to give him more time to prepare.
Hill is coming off a difficult season in which he compiled a 6.28 ERA in 63 appearances with Cleveland. He struggled with his control as a specialist against left-handed batters, walking 29 in 38 2/3 innings.
Headley is dealing with a calf injury, which has limited his production during camp. He's planning to do some jogging Friday as well. Headley said he feels great. Headley hit .250/.347/.400 in 520 at-bats last year.
"Everything that he's supposed to be doing at this point he's doing," he told the Baltimore Sun. "He's not ahead of schedule, he's not behind schedule. ... What that is, whether it's the day after opening day, whether it's a month after opening day, we just don't want any setbacks and we have not had any setbacks yet."
Machado emerged as a force in 2013. He played exceptional defense while batting .283 with 14 home runs, 71 RBI and an AL-best 51 doubles.
Street is dealing with a groin injury. He's planning to do some long-toss Friday, and should throw Saturday if he doesn't have a setback. Street posted a 2.70 ERA in 56 2/3 innings last year.
Callaspo could receive some time this season at first in a platoon situation, but his power numbers suggest he is not ideal for a corner position. He has never hit more than 11 home runs in a season and has not driven in more than 58 in any season since 2010.
Greinke is dealing with a calf injury, but continues to make progress. He's been able to throw bullpen sessions this week, and is ready to take the next step. It's still unlikely Greinke will make the trip to Australia, but does seem to be making progress.
Greinke posted a 2.63 ERA in 177 2/3 innings last year.
Belisario, who signed a one-year deal for $3 million in early December, struggled in his American League debut a year ago. The 2012 Dodgers standout managed a 5-7 record and 3.97 ERA in 2013. His strikeout total dropped markedly.
Ramirez is recovering after surgery to remove a polyp from his colon. He was able to run the bases Friday without issues. Ramirez said the knee injury that bothered him last season is no longer a problem. He added that he just needs to get into game shape. Ramirez said he would try to avoid sliding for a little while, however.
Ramirez hit .283/.370/.461 in 304 at-bats last year.
